Example 1–1 shows how to calculate the change of 50-I/O impedance from 25°C at
3.0 V to 85°C at 3.15 V.
Pin Capacitance
Table 1–11 lists the pin capacitance for Cyclone IV devices.
Example 1–1. Impedance Change
R
V = (3.15 – 3) × 1000 × –0.026 = –3.83
R
T = (85 – 25) × 0.262 = 15.72
Because
R
V is negative,
MFV = 1 / (3.83/100 + 1) = 0.963
Because
R
T is positive,
MFT = 15.72/100 + 1 = 1.157
MF = 0.963 × 1.157 = 1.114
Rfinal = 50 × 1.114 = 55.71

Notes to Table 1–11:
(1) The pin capacitance applies to FBGA, UBGA, and MBGA packages.
(2) When you use the VREF pin as a regular input or output, you can expect a reduced performance of toggle rate and tCO because of higher pin
capacitance.
(3) CVREFTB for the EP4CE22 device is 30 pF.
